What is dancer-plugin-adapter?

Dancer::Plugin::Adapter solves a simple but annoying problem for people building web apps with the Perl framework Dancer: what do you do when you want to use an external tool or service, but there's no pre-built plugin for it? Instead of writing a custom integration from scratch, this tool lets you wrap almost any existing Perl class and use it directly in your app as if a plugin already existed. You set it up by listing the classes you want to use in your app's configuration file, giving each a nickname. You also tell it how to construct the object, like passing in an API key, and choose how long the object should stick around. Then, in your app's code, you just call a function with that nickname to get your object and use it normally. For example, you could configure it to send email through a service like Postmark by just providing the class name and your API key in the config file. The project is flexible about how long it keeps each object alive, which matters depending on what the tool does. An object can last just for the current web request, for the duration of a user's session, or for the entire life of the application as a singleton. You can also tell it to create a fresh object every single time if the tool holds onto data that shouldn't be shared between users. This is useful for developers building apps in Dancer who want to quickly pull in a third-party service, like an email provider, an HTTP client, or a file utility, without hand-crafting the plumbing to manage it. It handles the setup and caching behind the scenes, so you can focus on actually using the tool. The README doesn't go into detail on limitations beyond the requirement that the class needs only static data to construct an object, but the project is straightforward by design: a pragmatic, "just-in-time" bridge between any Perl class and your Dancer application.
